I'm working on my second of two assessments ( I'm a novice ).
So far I've sorted new E Tails to metal socket plates, sorted reverse polarity at cooker isolation / socket switch ( still don't understand why fridge has n't got a problem with phase in neutrals at switch! ), got all the results for the EIRC, and fitted a new CU.

My ( hopefully ) last problem concerns main bonding as follows:

Cut 30' ish of 10mm E. Tested ends and got a continuity reading of 0.02ohms.
Fitted cable in situ ( clamp at water stop, then through wall to clamp at gas mains ( cable not cut ), then back into house to CU.

About five feet of this run sees cable running parallel in conduit and wall.

Now when I carry out continuity of main bond I get -00 ohms.

I have tested with leads not nulled and get a reading 0.02 ohms lower.

Is the parallel section causing this?

I know the reading must be below 0.05ohms but surely there must be some resistance.

You want to test it when it is all inn-situ.
Then disconnect from Met. One clip to 10mm other to r2 lead that is connected to clamp.
Then remember to remove lead resistance. If your not sure, follow the GN3 is the Best advice I can give you.
